Why book Southwest Airlines with JustFlightsFares
Southwest’s fares are simple to find but not always the lowest. Before quoting a price, our travel experts check four things.
We compare the second airport in your city
Southwest favors Dallas Love Field, Houston Hobby, Chicago Midway and Oakland. Depending on where you live, the other airport can be cheaper or closer, so we price both.
We tell you when Frontier undercuts Southwest
On Denver to Phoenix, Frontier’s cheapest round trip has been about $121, while Southwest flies the route 75 times a week. We show you both so you choose fare or frequency with the full picture.
We plan connections on a point-to-point airline
Southwest doesn’t route everything through one hub, so the best connection point changes by route. We find the one that keeps your travel day short.
We explain what each fare includes
Southwest has changed its fares and policies in recent years. We spell out what you are paying for before you book, so the price you hear is the price you get.

Southwest’s cheapest months are more spread out than most airlines’. January or February wins on 14 of the 20 routes, but Dallas–Houston is cheapest in November and Oakland–Las Vegas in October.
